PIPE-CUTTING IMPLEMENT.

Application led January 17, 1924. Serial No. 686,864.

To all whom I? 'may concern.' 1

Be it known that I, PAUL H. LniroLD a citizen of the United States,residing at Fort Wayne, in the county of Allen and State of Indiana,have invented certain new and 'use-- ful Improvements in a Pipe-CuttingImplement, of which the following is aspecitication.

This invention relates to pipe cutting implements, and has for one ofits objects to improve the construction and increase the efficiency andutility of the device.

Another object of the invention is to provide a device of this characterwherein the cutting elements are renewable without discarding theremaining parts of the implement.

Another object of the invention is to provide a device of this characterhaving means for adjusting the pipe engaging jaws. to operate on pipesof varying sizes.

With these and other objects in view the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention- Figure l is aside elevation, and

Fig. 2 is an edge view, of the improved implement;

Fig. 3 is a section, enlarged, on the line 3 8 of Fig. l;

Fig. 4 is a section, enlarged, on the line 4-4 of Fig. 1;

Fig. 5 is a detached view of one of the cutting blades;

Fig. 6 is a sectional detail of the adjustable joint of the improvedimplement; and

Fig. 7 is a plan view of a part of one of the body members.

The improved implement is designed more particularly for severing leadpiping and like relatively soft materials, and comprises coacting bodyportions 10-11 pivotally united.

One of the body members, for instance the member 10, is formed with atransverse slot with enlarged ends 25 and 26 and a contracted centralportion 27, as shown more clearly in Figure 7, while the member 11 isformed with an aperture to receive a clamp bolt 13, the body of the boltengaging the aperture in the member l1 and formed with an enlargement 28to engage alternately in the enlargements of the slot. A clamp nut 14 isapplied to the bolt, as shown, the object to be hereinafter explained.

The confrontingfaces of the body vportions 10 and 11 are preferablyreversely curved as shown, and bearing respectively upon the bodyportions are cutting blades 17 and 18 with their confronting edgesreversely curved and knife'edged. Intermediate the ends of blade 17 is aknifeedged cavity 19, while a similar knife edged cavity 20 is formed inthe. blade 18.

The confronting faces of the body members in advance of the pivot 13,are recessed to receive the cutting blades 17 and 18, the inner end ofthe recesses forming stop shoulders against which the inner ends of theblades bear and are thereby effectually supported from displacementlongitudinally of the body members.

Bearing upon the blade 17 is a holding plate 21, while a similar holdingplate 22 bears upon the blade 18.

As shown by dotted lines in Fig. 1, the inner ends of the holdingmembers 21 and 22 overlap the adjacent parts of the body members, andthus protect them, and supplement the holding force of the stop shoulcers.

The three parts 10-17 and 21 are coupled by clamp screws 23, while thethree parts 11, 18 and 22 are coupled by like clamp screws 24. By thismeans the cutting blades are firmly supported in position for use, butmay be readily detached for renewal.

In operating with the improved implement, the cutting blades 17 and 18are disposed upon opposite sides of the pipe to be severed, and pressureapplied to the hand grips 15 and 16 and rotary or oscillatory motionimparted to the implement to cause the knife edges of the blades to cutinto the pipe, the recesses 19 and 2O serving as teeth to increase thelefficiency of the cutting action.

The blades operating equally from opposite sides of the pipe sever thepipe uniformly and without reducing the size of the pipe or distortingit in any manner, leaving a square uniform end to the pipe.

By the arrangement shown when the bolt 13 is disposed with itsenlargement 28 in the enlarged end 25 of the slot the members 10 and 11will be in position to cause the cut- I and When-tbeorenlargement28oihthe bolt is disposed infthe enl'rged lend JQGo-,f-thel-slot, themembers 10 and 1l will be in position to cause the cutters 17 4and 181-to A,clasp nv larger pipe, as will be obvious.

The implement is simple in .jeonstiuotiom can be inexpensivelvmanufactured, of any suitable size or material. Y
